IMPROVEMENT IN PLOUGHS.

' EH12 l1th1lit mam-t it in the haters time no making not at in stun.

TO ALLWHOM IT MAY CONCERN: I

Be it known that I, ALEXANDER WRIGHT, of the city and county of Allegheny, in the State of Pennsylvania, have invented a new and-useful Improvement in Ploughs; andI do'hercby declare that the following is a full and exact description thereofl reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

The nature of my invention consists in constructing a plough which will answer the double purpose of a hill-side and a level-land plough, and so arranged that the face of the mould-board 'and'sh'are may be turned from the right to the left-hand side of the plough-beam by'sim-ply turning down sideways the beam and handles of the plough, and then securing the mould-board withvrelation to the beam and handles by means of a lever, the whole being constructed, arranged, and, operating in the manner hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. In the accompanying drawings, which form 'part of my specification- Figure 1 is a perspective view of my improvement in ploughs, and represents the face view of the mouldboard and share when they are turned to the right-hand side of the beam.

Figure 2 is a perspective view of the same, and represents theback of the mould-board and share, with their'faces turned to the left-hand side of the beam.

In the drawings, A represents the mould board and B represents the share, both of which present double workingedgesand faces. The mould-board and share are, by bolts, suitably secured to the block or piece marked R, which is pivoted to the land-side G at the point marked 1, (se e fig. To the back of the mouldboard A are attached braces 2, 3,'and 4,\Vhl0l l are connected to an arm, 5, which is at its lower end pivoted to the land-side G. On the back of the mould-board A, near the upper and back ends, are two projections, 0 and 0, which are provided with openings for the end of the lever m, which is held to the side of the beam D by means of the piece marked f. The upper end of the lever m is held by thepiece x, on thebrace n, for the handles e.

As the form, construction, and arrangement of the several parts of my improvement, and the relation that these parts bear to each other, will readily be understood by the skilful mechanic by reference to the accompanying drawings, Iwill therefore, without further description of its construction, proceed to describe its operation, which is as follows: When I desire to turn the face of the mould-hoardand share to the right-hand side of the plough-beam, I draw the lower end of the lever m out of the projection 0, and then turn the handles e and beam D downsideways, and then place the lower e nd oi' the lever m in the projection 0, and then raise up the handles and beams; and whenI desire to turn the face of the mould-hoard to-jthe left-hand side of the. plough-beam, I draw the lower end of" the lever out of the projection o, and then turn the handles and beam down to the right, and place the lower end of the lever m in theprojection o, and then raise up thehandlcs and beam to their proper position. v I I Ihe advantages of my improvement in ploughs consist in theiease and facility of changing the position of the mould-board and share. By the peculiar construction of the plough, I' obtain a central draught, which Ilsa great desideratnm in a pl'ough,l and give to the farmer a plough which will answer the double purpose of hill-side and level-land plough. I

Having thus described the nature, construction, and operation of my improvement, what I claim as of my invention is- V A plough, constructed, arranged, and operating substantially as herein described, and for the purpose set forth.

ALEXANDER WRIGHT.
